A codon-optimized recombinant ribonuclease, MC1 is characterized for its uridine-specific cleavage ability to map nucleoside modifications in RNA. The published MC1 amino acid sequence, as noted in a previous study, was used as a template to construct a synthetic gene with a natural codon bias favoring expression in Escherichia coli. Following optimization of various expression conditions, the active recombinant ribonuclease was successfully purified as a C-terminal His-tag fusion protein from E.

Ribonuclease (RNase) mapping of modified nucleosides onto RNA sequences is limited by RNase availability. A codon-optimized gene for RNase U2, a purine selective RNase with preference for adenosine, has been designed for overexpression using Escherichia coli as the host. Optimal expression conditions were identified enabling generation of milligram-scale quantities of active RNase U2.
